HomeDatabaseMysql TutorialCentOS 下 MySQL5.6.17编译安装

生产环境中,MySQL服务器上边最好什么服务都不要再安装!!!

一、准备工作:

# yum -y install make gcc-c++ cmake bison-devel ncurses-devel

 二、部署Mysql:

# tar zxf mysql-5.6.17.tar.gz # cd mysql-5.6.17 # cmake \ -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \ -DMYSQL_DATADIR=/usr/local/mysql/data \ -DSYSCONFDIR=/etc \ -DWITH_MYISAM_STORAGE_ENGINE=1 \ -DWITH_INNOBASE_STORAGE_ENGINE=1 \ -DWITH_MEMORY_STORAGE_ENGINE=1 \ -DWITH_READLINE=1 \ -DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock \ -DMYSQL_TCP_PORT=3306 \ -DENABLED_LOCAL_INFILE=1 \ -DWITH_PARTITION_STORAGE_ENGINE=1 \ -DEXTRA_CHARSETS=all \ -DDEFAULT_CHARSET=utf8 \ -DDEFAULT_COLLATION=utf8_general_ci # make && make install

三、配置Mysql:

1、设置权限:

# groupadd mysql # useradd -g mysql mysql # chown -R mysql:mysql /usr/local/mysql

 2、初始化配置:

# cd /usr/local/mysql # scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql

1 注意:在启动MySQL服务时,会按照一定次序搜索my.cnf,先在/etc目录下找,找不到则会搜索"$basedir/my.cnf",在本例中就是 /usr/local/mysql/my.cnf,这是新版MySQL的配置文件的默认位置! 2 在CentOS 6.4版操作系统的最小安装完成后,在/etc目录下会存在一个my.cnf,需要将此文件更名为其他的名字,如:/etc/my.cnf.bak,否则,该文件会干扰源码安装的MySQL的正确配置,造成无法启动。 3 在使用"yum update"更新系统后,需要检查下/etc目录下是否会多出一个my.cnf,如果多出,将它重命名成别的。否则,MySQL将使用这个配置文件启动,可能造成无法正常启动等问题。                                   

3、设置开机启动,并启动Mysql:

# cp support-files/mysql.server /etc/init.d/mysql # chkconfig mysql on # service mysql start //启动Mysql

4、配置mysql命令的变量,不然每次执行mysql命令都得要切换到安装目录

# vim /etc/profile

1 #------------------------Mysql命令的定义-------------------------# 2 export PATH=/usr/local/mysql/bin:$PATH

# source /etc/profile

四、配置用户:

MySQL启动成功后,root默认没有密码,我们需要设置root密码。

# mysql -uroot mysql> SET PASSWORD = PASSWORD('You_password'); //You_password为你要设置的密码

设置root用户可以远程访问:

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.%' IDENTIFIED BY 'You_password' WITH GRANT OPTION;  //红色的You_password为远程访问时,root用户的密码,可以和本地不同。

五、配置防火墙

防火墙的3306端口默认没有开启,若要远程访问,需要开启这个端口
打开/etc/sysconfig/iptables
在“-A INPUT –m state --state NEW –m tcp –p –dport 22 –j ACCEPT”,下添加:

1 -A INPUT -m state --state NEW -m tcp -p -dport 3306 -j ACCEPT

然后保存,并关闭该文件,在终端内运行下面的命令,刷新防火墙配置:

# service iptables restart

部署完毕!

扩展!

CentOS 7中默认使用Firewalld做防火墙,所以修改iptables后,在重启系统后,根本不管用。
Firewalld中添加端口方法如下:

firewall-cmd --zone=public --add-port=3306/tcp --permanent firewall-cmd --reload

Explain the InnoDB Buffer Pool and its importance for performance.Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.
